Professor Bennett is gathering materials she will use in an upcoming class she is teaching. The class is new and there is currently no textbook for it on the market. Professor Bennett compiles articles from different sources, which she then takes to a local photocopying shop to have photocopied for use by her class. The photocopying shop refuses to copy the materials for Professor Bennett until she provides copyright releases from each of the authors. Professor Bennett argues that no such permission is needed. Who is correct and why?
